Easy to install simple to use

Haven't seen a major power difference but has definitely improved fuel economy. Only problem I've had with it is it has froze up on me twice.

Works as discribed

Simply plugged it in and problem solved. No more constant shifting between 25-45 MPH. Dealer told me I would get used to it and I never could. Was considering trading for another brand, even though I love this truck and now it runs like a V8 should.
